The reverse-acting, SRX rupture disc has a cross scored design for use with vapor services only. It offers a superior service life in heavy pulsating and cyclic duty, and performs reliably under less than ideal installation conditions.
- The score configuration controls the disc opening and enables the disc to rupture without fragmentation
- Effective when used to isolate Safety Relief Valves
- Will sustain process operating pressures as high as 90% of the stamped disc rating
- Withstands full vacuum, or back pressure service in magnitudes equivalent to the stamped burst pressure.
- Special seating configuration allows this rupture disc to perform reliably, even under less than ideal installation conditions
- All manufacturing ranges are below the specified burst pressure
- Materials of construction include: 316/316L SST, Inconel®, Monel®, Nickel, and Hastelloy®. Protective coatings such as fluoropolymer and polyurethane are available to enhance corrosion resistance
- Effective in VALVEGUARD protection of expensive Pressure Relief Valves and Safety Relief Valves
